20 Claims. (Cl. 38-78) This invention relates in general to atirons ofthe domestic variety, and pertains more particularly to an iron capableof spraying the fabric undergoing a pressing operation with either oftwo separate and distinct liquids.

One object of the invention is to provide an electric iron equipped witha reservoir divided into two compartments, together with associatedpumping mechanism by which liquid from either of the two compartmentscan be readily atomized and sprayed onto the material being ironed. Inits more specific aspects the invention has in View the dual utilizationof the iron for spraying plain water onto the fabric or for spraying aprepared starch solution thereon. For example, in the ironing of mensshirts, it is frequently desirably that the collars and cuffs bestarched, whereas the remainder of the shirt need be only damp ironed.

With the above object in mind it will be recognized that there is a needfor a double reservoir iron that may be quickly shifted from one liquidto another, and the instant invention has for an aim the provision ofpumping structure whereby this end may be rapidly and effectivelyaccomplished. 4

Another object of the iron is to permit the spraying of either of twoliquids at controlled or selected rates of flow.

Another feature of the invention resides in the employment of areservoir and pump arrangement that will not materially increase theover-all weight of the iron.

A further object of the invention is to produce a double purposemoistening iron that will not require any heat `for the application ofmoisture to the fabric, thereby leaving the heat generated by theheating element for the raising of the soleplate temperature. Stated`otherwise, it is a desideratum of the invention to refrain fromwithdrawing heat from the soleplate for conversion of the differentliquids to a modified state by temperature change, the entire heatsupply instead being made available for the pressing operation itself.

Further, another object of the invention is to permit the use of theiron as a dry type of iron whenever desired.

Other objects will be in part obvious, and in part pointed out more indetail hereinafter.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereafter set forth and the scope of theapplication which will be indicated in the appended claims.

Fig. 7 is a view similar to Figs. 3 and 5 but showing the modificationof Fig. 6; and

Fig. 8 is a sectional view taken substantially in the direction of line8 8 of Fig. 6.

Referring first to the embodiment forming the subject matter of Figs.1-4, it will be observed that the iron selected for the purposeof'exemplifying this particular embodiment comprises a soleplate 10having embedded therein a conventional encased heating element 12, theheating elementbeing in circuit with a thermostatic switch bearing thereference numeral 14. The switch 14 is equipped with an upstanding shaft16 having at its upper end a manipulating knob 18 providing a facile wayby which the switch may be adjusted for various ironing temperatures.Shown in circuit relationship with the heating element 12 and the switch14 is a pair of electrical conductors 20 and 22, these conductorspassing upwardly through a portion of a handle member 24 and continuingin the form of a flexible connector 26 by virtue of which the iron maybe connected to the customary 60 cycle household electrical outlet.

Surmounting the soleplate 10 is a reservoir designated in its entiretyby the numeral 28, the reservoir having a longitudinally directedpartition 30 which divides the reservoir into two compartments 32 and34. However, the partition need not in every instance be entirelylocated, for it will be appreciated that in some situations it will bedesirable to have the compartments 32 and 34 of unequal volumetriccapacities, depending chiefly on the respective demands for a givenliquid. While it is possible for these compartments 32 and 34 toaccommodate any particular liquid that may be desired in dampening thefabric undergoing a pressing operation, it is within the specificcontemplation of the invention to utilize one of the compartments forthe containing of a starch solution whereas the other compartment willbe utilized for the storage of plain water. Therefore it will be assumedin the course of the ensuing description that the compartment 32contains the starch solution and that the compartment 34 containslonlywater. Providing access to the compartment 32 is a filler plug 36, theremoval of which permits the introduction of the starch solution to thisparticular compartment. A similar filler plug 38 is employed inconjunction with the compartment 34 for permitting the introduction ofwater to this particular compartment.

For the purpose of spraying the contents of the compartment 32 upon thefabric material there is a rst nozzle assembly 40, this nozzle assemblybeing capable of atomizing the liquid starch into a tine spray or mist.A similar nozzle assembly 42 is utilized in the atomization of the watercontained in the compartment 34. From an inspection of Fig. 1 it will bediscerned that the nozzle assembly 42 consists of a tubular boss 44axed, as by brazing, to the shell of the reservoir 28, the tubular boss44 having a passage 46 extending therethrough for the purpose ofconducting the water under pressure to a disk 48 having a small orifice50 therein. The disk 48 is retained in place by reason of a threaded nut52 having engagement with the forward end of the tubular boss 44. Ashereinbefore indicated, the nozzle assemblies 40 and 42, are of likeconstruction and therefore it is not felt necessary to describe theassembly 40 in detail. However in passing it might be mentioned that theorifice in the disk of the assembly 40 which would correspond to thedisk 48 in the assembly 42 might be in certain situations of larger sizethan that actually shown in the cross sectional make-up of the nozzleassembly 42 inasmuch as the starch solution would normally be of greaterdensity and viscosity than plain water. Also, depending upon thespecific liquids to be pumped, various disks 48 might be supplied withthe iron, each equipped with an orice of preferred dimensions tofacilitate the discharge of any of certain liquids that may be desired.

Up to this point nothing has been said with regard to the means by whichthe particular liquids confined, in the compartments 32 and 34 aretransmitted to the nozzle assemblies 40 and 42. In this regard it isplanned that fa pair of pump mechanisms 54 and 56 -be employed and hereagain these mechanisms maybe of similar construction. Therefore,returning to Fig. l where the pump mechanism 56 is shown in sectionaldetail, it will ybe observed that this particular mechanism includes vavertically directed cylinder 58 in which there is disposed-a reciprocalpiston 60. The lower end of the cylinder is equipped with a threadedplug 62 having `an aperture 6'4V passing therethrough; The lower end ofthe aperture 64 is in direct communication with the compartment 34 andthe upper end of this aperture is slightly beveled for the accommodationof a ball check valve 66. Actually by exercising care in the design ofthe dimensions of the aperture 64 the ball check valve 66 may bedispensed with but for the purpose of facilitating-an understanding ofjusthow the pump mechanism 56 functions, it is felt desirable to`illustrate .the ball check 66. Further included as a partof the pumpmechanism 56 is a forwardly directed tubular boss-68 circumferentiallyengaging the inner end of the rst-mentioned tubular boss 44. Heldcaptive within the bore of the tubular boss 68 is a coiledsprlng 70which bears against a second ball check 72. As can be seen from thedrawings, the ball check'72 in turn bearsv against a-seat formed by anaperture 74 leading into the cylinder 58.

As can be seen from Fig. 3, each of the pump mechanisms 54 and 56 havepiston rods 76 and 78, these piston rods being integral with theirrespective pistons such as the piston designated by the numeral 60 inFig. 1. Circumscribing the piston rods 76 and 78 are coil springs 80 and82, these coil springs bearing against the under side of enlarged heads84 and 86 at the upper ends of the two piston rods 76 and 78. By havingthe lower ends of the springs 80 and 82 abut the upperside of a platformor floor member 88, it will be appreciated that these springs 80 and 82may be kept under slight compression and in this way are instrumental inhelping to elevate the piston rods 76 and/78.

For the purpose of rapidly and repeatedly overcoming the biasing factionof the springs 80 and Sp2-'there is provided an electromagnetic motor unit 90. The electromagnetic motor includes a stack of E-shapedlaminations forming a core 92, the core having its central leg encircledby a coil 94 which may be energized by reasonof a pair of conductors 96and 98 in circuit witha switch generally designated by the numeral A100.AAs with the conductors 20 and 22, these last mentioned conductors 96and 98 receive power via the connector 26, .being in parallel with saidconductors 20 and 22. In this connection it will be discerned that theswitch 100 includes a pair of s witch arms 102 and 104 each having acontact 106 at its free end. The Vswitch unit 100 is retained in placewithin a recessed portion of the handle 24 as by a bolt member 108. Inriding relationship with the switch arm 102, which yis a resilient arm,is a slidable button or cam 110 having its upper surface serrated at 112to facilitate the sliding manipulation of this button. Due to the camaction of the slidable button 110 it will be understood that the switcharm 102 is deected downwardly so that the contacts 106 are brought intoengagement `whenever the button 110 is moved forwardly.

Also lconstituting part of the electromagnetiornotor of the armatures114 and 116 lying opposite their pivotally connected ends `serve asactuators for the pump mechanisms 54 and 56, inasmuch as the under sideof these armature ends bear directly against the upper surfaces of theheads 84 vand 86. Thus it will be seen that the armatures 114 and 116when vibrated or oscillated about their pivot pin 118 force the pistonrods 76 and 78 downwardly due to the magnetic attraction of the core 92with the two armatures 114 and 116. The springs 80 and 82, of course,aid in raising the armatures 114 and 116 and in this way it will be seenthat the armatures move both upwardly and downwardly in an oscillatoryfashion.

In order to accommodate the electromagnetic motor 90, the handle member24 is recessed at 120, the platform or floor 8S serving as the bottomwall for this particular recess 120. A yoke 122 serves the function ofproviding a journal 124 for a control shaft 126. A knob 128 is mountedat the upper end of the control shaft which is also journalled within aforward portion of the handle member 24 and at the lower end of thisshaft there is carried a rotary cam 130. The purpose of the cam 130 isto control or govern the amount of vibration that the armatures 114 and116 can be subjected to by the electromagnetic action of the core 92.With this aim in mind, specic reference should now be had to Fig. 4where the rotary cam is pictured in perspective detail. In thisparticular ligure it can be discerned that the rotary cam 130 isconfigured so as to provide a segmental promontory 132.y which is ofsufficient width so that it will overlie both of the armatures 114 and116 and when so overlying both of the armatures will preclude thearmatures from vibrating upwardly and downwardly due to the blockingaction of this promontory 132. Since it is desired at times to controlthe ilow or rate of atomization of either of the liquids being pumpedfrom the compartments 32 and 34 out through the nozzle assemblies 40 and42, it is within the purview of the invention to form the rotary camwith inclined segmental surfaces 134 and 136. In this way, when thesurface 134 is overlying one of the armatures 114 or 116, thisparticular armature will be permitted to vibrate through only a portionof its total possible angular travel. Consequently the displacement ofthe particular pump 54 or 56 with which the partially blocked armatureis associated will be lessened with the consequence that its volumetricdischarge or output is correspondingly reduced. As can be seen from Fig.4, the combined segmental areas 132, 134, and 136 total approximately180, leaving a dwell portion 138 which is of adequate elevation so thatwhen this dwell portion 138 is overlying either of the armatures 114 or116, then the particular armature which is subjacent the dwell portion138 will be permitted to vibrate without impediment and the fullcapacity of the particular pump mechanism associated with the unhamperedarmature will be realized.

As illustrated in Fig. 2, the knob 128 has been rotated through an angleof substantially 90 so that the armature 116 is. blocked by thepromontory 132 (see Fig. 3), leaving armature 114 free to vibrate to itsfullest extent. By blocking the armature 116 it will be understood thatthe pump mechanism is inactivated and that no liquid will be forced fromthe compartment 34. Stated otherwise, when the knob 128 is in theposition shown in Fig. 2, the iron is being used to apply the starchsolution from the compartment 32 to the fabric undergoing the ironingoperation, this taking place via the nozzle `assembly 40. Of course, inactual practice, the armatures vibrate at a rate of times per second(when connected to a 60 cycle source) and the total displacement of eachof these armatures is only a fraction of an inch; hence it will beappreciated that the slope or inclination of the areas 134 and 136 issomewhat exaggerated and that the promontory 132 does not have to dependdownwardly to the extent shown in order to fully block either of thearmatures 114 and 116. However, this exaggerated condition pictured inFig. 4 is believed helpful to a facile understanding of the invention.

Passing now to a discussion of the second embodiment, the same referencenumerals have been applied to identical parts, and the salientdiiference between the embodiment pictured in Fig. 5 from that in theearlier referred to figures resides in the use of a reciprocable cammeans designated generally by the reference numeral 140. As will be seenfrom Fig. 5 this reciprocable cam means includes a bar 142 journalledfor transverse sliding movement in the yoke 122. To enable the user ofthe iron to quickly bring into eifective blocking operation a promontory144 formed integral with the bar 142 is a pair of push buttons 146 and148. As indicated in Fig. 5, the push button 146 has been pressed so asto move the promontory 144 into blocking relationship with the armature116, thereby conditioning the iron for a starch applying operation. Forthe purpose of maintaining the cam means 140 in its shifted position,there is provided a recess 150 housing a coil spring 152, the lower endof the coil spring bearing against a ball 154. The ball 154 in turn isengageable in any one of three notches 156, 158, 160, the notch 156currently being in use to maintain the cam means 140 in its picturedposition. However, depression of the push button 148 will result in thepromontory 144 being moved to the left and when the ball 154 rests inthe notch 158, then the promontory will straddle both the armatures 114and 116 to prevent the operation of either and of course when the button148 is fully pressed to the left then the ball 154 rests in the notch160 to hold the promontory.

144 in superimposed relation with the armature 114, thereby blocking thevibratory movement of said armature 114.

From the preceding paragraph it will be discerned that the embodiment ofFig. 5 differs in its function by reason of the reciprocable cam means140 in contradistinction to the rotary type of cam means 130 describedin the earlier embodiment.

In some instances it will be desirable to utilize only a single pumpmechanism 54 or 56 together with a single armature 114 or 116.Consequently the modification of Figs. 6-8 concerns the utilization ofonly a single pump mechanism which has been given the reference numeral162 in order to distinguish it from the pump mechanisms 54 and 56although, in general, as will presently be recognized, there isappreciable similarity between the pump mechanism 162 and the earlierreferred to ones 54 and 56. The pump mechanism 162 comprises avertically directed cylinder 164 in which a piston 166 is mounted forreciprocable movement. The lower end of the cylinder 164 is of -aT-shaped configuration inasmuch as a horizontal cylinder 168 isemployed, the horizontal clyinder 168 establishing communication betweenthe compartment 32 and the compartment 34. Communication between thevertical cylinder 164 and the horizontal cylinder 168 is effected bymeans of a threaded boss 170 integral with the cylinder 168, which bossis received in the lower end of the cylinder 164. The boss 170corresponds to the plug 62 having therein an aperture 172 at the upperend of which is disposed a ball check 174.

The cylinder 168, as already indicated, provides a means of conductingliquid from either of the compartments 32 or 34 and to control selectivewithdrawal of liquid from either of these two compartments it isenvisaged that a reciprocable piston 176 be slidably disposed within thebore of the cylinder 168. As best seen from Fig. 7, the piston isequipped with a piston rod 178 extending in the direction of thecompartment 34. To the free end of the piston rod 178 is pivotallyattached a crank element 180 by means of a pin 182. The crank 180 issecured to the lower end of an upstanding shaft 184 having its lower endjournalled in a cup bearingl86. The shaft 184 extends upwardly through agrommet 188 in the shell of the reservoir 28, continu ing upwardlythrough a portion of a somewhat modified handle member 190 andterminating in a knob 192 by which the shaft 184 may be rotated to shiftthe piston 176 to either side of the aperture 172 and thereby determinefrom which compartment 32 or 34 liquid is to be withdrawn. When theshaft 184 is viewed from above, it will be recognized that the clockwiserotation of the shaft is instrumental in moving the piston 176 to theleft in Fig. 7, thereby establishing communication with the compartment34, and counterclockwise rotation moves the piston to the right toconnect the compartment 32.

The upper end of the piston 166 has integral therewith a piston rod 194corresponding to the piston rods 76 and 78 and encircling this pistonrod is a coil spring 196 bearing against the under side of an enlargedhead 198. Here again, the spring 196 has its lower end abutting aplatform or oor 200 so that when the spring 196 is under a slightcompression, the piston 166 is urged upwardly. An electromagnetic motor202 provides the actuating force for causing the piston 166 toreciprocate rapidly within the cylinder 164, this motor 202 beinggenerally similar to the earlier described motor 90. However, thesalient ditference between the two motors resides in the fact that thematter motor 202 is equipped with only a single armature 204 instead ofthe twin armatures 114 and 116. Returning to a more complete descriptionof the pump mechanism 162, it will be seen from Fig. 6 that this pumpmechanism is provided with a forwardly extending tubular portion 206having contained therein a coil spring 208, one end of which bearsagainst a ball check 210 for the purpose of sealing an aperture 212formed in the Vertical cylinder 164.

The opposite `end of the tubular portion 206 has communication with anozzle assembly designated in its e11- tirety by the numeral 214.Inasmuch as this nozzle assembly is identical in construction witheither of the nozzle assemblies 40 and 42, the duplication of partscontained therein has been denoted by the same specific referencenumerals lapplied to Fig. l. However, owing to the fact that a singlemechanism 162 is employed in the currently described embodiment only asingle nozzle assembly 214 is required for the shifting of the piston176 determines from which tank the liquid is to be withdrawn, the nozzleassembly 214 serving to spray either the starch solution from thecompartment 32 or the water from the compartment 34, these liquidshaving been suggested hereinbefore.

Reference to Fig. 8 will show that a longitudinally disposed partition230 is utilized in forming the compartments 32 and 34, this partition230 having been differentiated from the partition 30 inasmuch as itconsists in the exemplified embodiment of several sections or panels topermit the pump mechanism 162 to be centrally located. Other than theparticular construction mentioned, it will be appreciated that thepartition 230 serves the same oice as the one referred to earlier.

With the foregoing details in mind, it is believed that the operation ofthe several embodiments herein disclosed will be manifest. However, toassure a thorough understanding of the operation associated with eachembodiment, a brief sequence will be given and in this connectionreference should again be had to Figs. 1 4. It will be recalled thatthis embodiment utilizes a pair of nozzle assemblies 40 and 42, theselection of liquid from either the compartment 32 or 34 being made byrotation of the knob 128. For instance, when the knob 128 is movedcounterclockwise to the position of Fig. 2, then the iron is conditionedfor the spraying of the starch solution from the compartment 32 by wayof the nozzle assembly 40 inasmuch as the promontory 132 then blocks thevibration of the armature 116. If a lesser amount of starch solution isdesired then a reduced ow of starch solution a lesser angle than thedepicted in Fig. 2, for then a portion of the surface 134 will lie abovethe armature 114 i-nstead of the ldwellportion 138. Thusmovement of.the-armature 1.114 is limited tota certain extent andthe full pumpingcapacity of the pump mechanism 54 is not achieved. However, the`promontory 132 will overlie the armature 116 just as before althoughnot to the full angular extent brought about when in the position ofFig. 2.

From Fig. 1 it can be seen-that thepumping action is etected rapidly,the upward stroke of the-piston, due to the:vibratoryy action of themotor90,tending to evacuate the cylinder V58. The evacuation, of course,need not be complete to draw liquid upward-ly past the check valve 66.On the downward or reverse stroke, the entrapped liquid will be-forcedthrough the aperture 74 past the check 72 through the nozzle assembly44, said assembly acting toy atomize-the liquid into ane mist or spraywhich is directed at a downward angle onto -the vfabric being pressed.

As already indicated,they embodiment of Fig, 5 is similar to that ofFigs. 1-4 and in this-particular lsituation the pressing of the pushbutton 146 is responsible for having the promontory 144 moved into asuperimposed relationship with the armature 116 -thereby blocking thevibration of this particular armature. As illustrated in Fig. ;5, theiron is conditioned for the pumping of the starch solution fromcompartment 32. When a plain water spray is desired, then the operatorpresses Athe button 148 to move the cam means 140 in an oppositedirection and to bring the promontory 144 in juxtaposition with theamature 114. A central positioning of the cam means 140 lwill cause botharmatures 114 and 116 to be blocked and no pumping of liquid from eithercompartment is then accomplished.

It might be explained at this time that in the embodiment of Figs. 1-4and Fig. 5, the-movement of either the promontory 132 or the promontory144, respectively, to acentral position blocks the reciprocatorymovement of both of the armatures and in this way the iron serves thefunction of a dry type of iron just as though the switch button 112 hasbeen moved to an off position. Hence, it will be appreciated that thereis made available to the user of the iron two courses of actionconditioning the iron for dry operation: either the user may deenergizethe electromagnetic motor 90 or he may block the movement of thearmatures 114 and 116 constituting a part thereof.

In operating the embodiment of Figs. 6-8 substantially the samemanipulation is undertaken as in the embodiment of Figs. l-4 but insteadthe knob 192 is responsible for moving the piston 176 to either side ofthe aperture 172 to physically block the entrance of liquid from eitherthe compartment 32 or 34 to the single pump mechanism designated by thenumeral 162. When the valve mechanism, which includes the piston 176, isactuated in a direction to move the piston to the right as viewed inFig. 7 then the pumping of a starch solution from the compartment 32 isetected whereas movement of the piston 176 in an opposite direction isresponsible for conditioning the iron for the pumping of plain water.The point to be appreciated here is that only a single nozzle assembly214 is incorporated into the iron in contradistinction to the twinnozzle assemblies 40 and 42 employed in the two earlier referred toembodiments.

As many changes could be made in the above construction and manyapparently widely diierent embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.

AIt is also to be understood that the Ilanguage used inthe-following'claims is intended to cover all of the generic andspecific features of the invention `herein described and al1 statementsof the scope of the invention which, as a matter of language, mightbesaid to fall therebetween.
